Efficient extraction and determination of Au(III) ions from acid mine drainage and water samples using silica gel immobilized with .

The analysis of gold, which is a precious metal with limited resources, in environmental samples is crucial for the sustainable utilization of natural resources. Therefore, in the present research we have aimed to develop a novel and environmentally friendly bioadsorbent, loaded on silica gel (BB@Si), with outstanding adsorptive properties that can be implemented for quantitative recovery of Au(III) ions the solid phase extraction (SPE) technique. After characterizing the developed adsorbent using FTIR and SEM techniques, we conducted a detailed investigation of the critical parameters that influence the extraction performance of Au(III) ions.

The systematic evaluation of an embodied control interface for virtual reality.

Embodied interfaces are promising for virtual reality (VR) because they can improve immersion and reduce simulator sickness compared to more traditional handheld interfaces (e.g., gamepads).

Cloning, biochemical characterization and molecular docking of novel thermostable β-glucosidase BglA9 from Anoxybacillus ayderensis A9 and its application in de-glycosylation of Polydatin.

This study reports a novel BglA9 gene of 1345 bp encoding β-glucosidase from Anoxybacillus ayderensis A9, which was amplified and expressed in E. coli BL21 (DE3): pLysS cells, purified with Ni-NTA column having molecular weight of 52.6 kDa and was used in the bioconversion of polydatin to resveratrol.

The COX2 genetic variants in oral squamous cell carcinoma in Turkish population.

Oral squamous cell carcinoma (OSCC) is a common type of cancer that genetic and environmental factors also lifestyle habits, infections play important roles in the pathogenesis of disease. Cyclooxygenase 2 (COX2) is the inducible isoform of enzyme which convert arachidonic acid to prostaglandins. It was known that alterations in COX2 gene functions contribute to the inflammation process thus induce cancer progression, including cell proliferation, apoptosis, adhesion, invasion and metastasis.

Nonomuraea insulae sp. nov., isolated from forest soil.

Strain H2R21, a novel actinobacterium, isolated from a forest soil sample collected from Heybeliada, Istanbul, Turkey, and a polyphasic approach was used for characterisation of the strain. Chemotaxonomic and morphological characterisation of strain H2R21 indicated that it belongs to the genus Nonomuraea. 16S rRNA gene sequence similarity showed that the strain is closely related to Nonomuraea purpurea 1SM4-01 (99.

Saccharopolyspora hattusasensis sp. nov., isolated from soil.

A Saccharopolyspora strain, designated CR3506, isolated from a soil sample collected from Sungurlu, Corum, Turkey, was examinated using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence analysis showed that the strain is closely related to the type strains of Saccharopolyspora spinosa NRRL 18395 (99.1%), Saccharopolyspora phatthalungensis NRRL B-24798 (98.

Redesigning pH optimum of Geobacillus sp. TF16 endoxylanase through in silico designed DNA swapping strategy.

Thermoalkaliphilic xylanases are highly desired and of great importance due to their vast potential in paper pulp and bleaching processes. Here, we report rapid, cost-effective, and result-oriented combinatorial potential of in silico DNA swapping strategy to engineer the pH optimum of industrially crucial enzymes, particularly engineering of Geobacillus sp. TF16 endoxylanase for alkaline environments.

Fontibacillus pullulanilyticus sp.nov. isolated from soil.

Gram stain-negative, motile, catalase-, and oxidase- positive strain, designated DSHK107(T) was isolated from soil of Cukurova University campus in Adana, Turkey. Its taxonomy was investigated using a polyphasic approach. The strain grew at 20-42 °C (optimum, 30 °C), at pH 6.
